Liliana 2.0 is easily my favorite magic card. She is the best planeswalker ever, barring big daddy Jace, who is always a given. Liliana packs so much power in so little words. Her abilities are so simple, yet powerful, very elegant. At a low cost of 1BB she can be deployed as early as turn 2 with the proper mana ramp. Her second ability lets her clear the board of any early game creatures like the threatening tarmogoyf or stoneforge mystic. Her discard ability is just too powerful, destroying your opponents hand in a matter of turns, while setting up for more sacrifices or a huge blowout with her ultimate. And that's just one card in a deck.
